Frank L. Darlin Patented June 9, 1936 RECEPTACLE, COVER THEREFOR, ANDMEANS FOR RELEASING THE COVERS FROM THE RECEPTACLES Frank L. Darling,Douglaston, N. Y., assignor to Glen-Dar Can 00., a corporation ofDelaware Application December 18, 1934, Serial No. 758,135 10 Claims.(01. 22o 4s) The present invention relates to certain new and usefulimprovements in the covers of receptacles and has for its objects .tomodify and improve the structure disclosed in my patent issued January8, 1935, No. 1,987,550, so as to reduce the expense of manufacturing andassembling the cover and the cover releasing and lifting lever, as wellas to strengthen the structure 50f the cover at the place where thelever is located and reduce to the minimum the deforming of the cover inreleasing the same from the receptacles;

The invention also has for its object to eliminate the angularoffsetting of the cover-bead beneath thehood and to extend the frontwall of the hood as an unbroken or continuous wall from the top. of thecover to the bead.

Again, it is an object to provide the cover skirt with indentationslocated adjacent the hood to receive the trunnions of the lever andalso, if desired, to serve in cooperation with lugs spaced apart I20degrees, 'more or less, as a snap-on interlocking means between thecover and the receptacle;

' A further object is to provide all improvements hereinbefore mentionedand yet retain the advantages of the structure disclosed in myapplication aforesaid.

H Figure 9 is a detail section on the line 99 of Figure 1. 65 I In thedrawing, in which like numerals and letters of reference indicate likeparts in all the figures, l represents a can or other similar receptaclewhose mouth edge is provided with an outwardly formed bead 2. Aside fromthe presence of the bead 2 the remaining structure of 5 the can orreceptacle is not material to the present invention, but may be modifiedand formed to suit the varying conditions met with in the trade,

7 3 designates the cover which is provided with a depending skirt 4preferably having a pair of lugs 10 5 disposed approximately 120 degreesapart. The bottom of the skirt 4 is provided with an outwardly formedbead B which extends around the entire skirt as a substantially truecircle, it being bulged out slightly as at 6w adjacent the hood 1 Thehood 1 projects radially outwardly from the remainder of the skirt 4 andhas its front or outer wall continuous from the top of the lid 3 to thebead portion 6a (see Figures 2, 3 and 4).. In this respect it differsfrom the construction di'sclosed in my prior application where the lowerportion of the hood is shown cut away by a transverse slot, leaving thebead of the cover standing alone where it passes beneath the hoodproper. In my application aforementioned the head of the cover isoutwardly offset to conform to the outline of the hood, whereas in thepresent in.- stance the bead is not offset angularly, but simply bulgesoutslightly in a curve which, to the eye of an ordinary observer, doesnot depart from a true circle; hence the general appearance of the lidis not greatly different from that of an ordinary lid. By continuing thefront wall of the hood 1 down to the bead at 6% as an unbroken structurethe bead is strengthened and hence is less likely to be distorted duringthe act of releasing and lifting the cover from the can.

The side walls 8 of the hood are inclined outwardly and converge towardone another. At the bottom of the side walls 8, and above the bead 406-641, the side walls 8 are interrupted by pressing the skirt inwardlyto form laterally elongated indentations 9 and straight side walls ID.The hood 1 and indentations 9 are formed in practice by stamping dieswhich have provisions forforming the straight walls Ill, andsimultaneously providing openings l l in the side walls 8 by shearingthe material (see Figures 4, 7 and 8). It will therefore be seen thatthe indentations 9 provide convenient recesses for the trunnions I4 ofthe lid releasing and lifting lever l2 after thetrunnions M are passedthrough the apertures II in the side walls 8. These indentations 9 maybe formed so as to serve the double purpose of providing recesses forthe trunnions l4 and coopby, when the cover and can are assembled,theshort arm 13 will lie within the hood 1 in contact with the bead 2 ofthe can and terminate about on a level with the top of the bead and thelong arm of the lever i 2 will lie in contact with the body of the can.Preferably the trunnions I 4 are designed so as not to lie in alignmentwith each other. (See Figures 2 and 7). By forming the trunnions so thatthey do not lie in alignment and by locating the holes arm the sidewalls 8, the lever l2, when the cover is "off the can, willautomatically'assume the dotted line-position shown in Figure 3, as inthe construction disclosed in my previous application above referred to.

7 As will be clear from Figure 8, it is a simple matter to assemble thelever 52 and top 3, since it is only necessary to squeeze the parallelportions of the lever '42 together in order to enable the trunnions tobe inserted into their respective bearing apertures ii in which they arethen retained by the spring action of the lever. The cover may beprovided with a sealing gasket l5 if desired, this being preferableWhere a vacuum or air-tight closure is desired.

By the construction illustrated in the accompanying drawing it will beobserved that I am enabled to make the hood '1 considerably shallowerthan the corresponding hood illustrated in my previous application, andamalso enabled to make the skirt of the cover proportionately of lessdepth than that disclosed in my aforesaid application. Inthe act ofremoving the cover from'the can it is to be observed that the lever l2does not fulcrum on the trunnions Hi, but the lever bears against thetwo beads 2 and 6a, the short arm 'IS of the lever riding up and overthe bead 2 as the long arm I2 is pulled from the full line positionshown in Figure 3 to the dotted line position. While the upper end ofthe short arm. l3 rides on the bead 2, the long arm presses against thebead 6a which constitutes the second point of leverage. The trunnions l4serve not only as a means for retaining the lever on the cover, but incooperation withthe angled sides 8 of the hood and the short armportions E3 of the lever serve as automatic means to incline the longarm of the .lever outwardly (see dotted lines, Figure 3) when the coveris off the can.

Hence it will be seen that while I have improved the structure disclosedin my application aforesaid, I have retained the advantageous featuresthereof.

From the foregoing description, taken in connection with theaccompanying drawing, it is believed that the complete construction andadvantages of the invention will be clear to those skilled in the art towhich it appertains.
